    Summary

    April 28th, 2015. The Avengers work together again, going to the small country of Sokovia to retrieve the scepter from HYDRA, kicking off the events of Age of Ultron. A prisoner uses their arrival as a distraction and escapes, wreaking havoc. It turns out the prisoner is Harry Potter, wizard extraordinaire and Tony Stark's fiance, missing for almost five years.

    Of course Tony's not going to leave him there, and Steve Rogers can stuff his concerns.

    Planning to take this through Infinity War and a much-changed Endgame, unless I end things with Infinity War.

    Summary

    Harry Potter was absolutely, unashamedly, done.
    First, Voldy uses a Ritual to bring his pasty snake ass back to life, killing Cedric- which, by the way, thanks for the extra trauma.
    Second, Harry goes through a lovely year of being tortured with a damn writing utensil and ends up in Azkaban after the Battle of the Department of Mysteries- which Dumbledore chose not to prevent.
    So, y'know, fuck him.

    One year later Harry gets released... only to find out he has to go back to the Dursley's; which, no thanks- his cell in Azkaban was looking rather comfy, in comparison to that hell hole.

    Luckily for the plot, Sirius knows of Harry's true parentage and decides it'll be better for everyone if Harry just pops over to America to be emancipated so he could then live with his godfather; it's not like this Tony Stark guy will put up much of a fuss right?
    Right???

    Gods, Mercenaries, Super-spies, romance and a Headmaster who won't let his weapon go-

    What could possibly go wrong?

    Summary

    Harry meets Merle on a rooftop in Atlanta. After twenty questions, he finds himself enthralled with the gruff man and decides to follow him and his brother (and maybe their group).

    Or maybe, Death feels that Harry deserves a second – albeit fucked up – chance at life. Only Luna knows if Death knows what he is doing!

    Throw in a George, Ron, Draco, Daryl and Michonne and see what you will get.

    Some characters stay alive, other characters will die, albeit in a different way or for a different reason. A few OC’s, since there are some random characters and American witches and wizards.
